Depends on if you need two phases. If you only need one phase, then the LM5148 is an option (and this is stackable to two phases if needed).
Typically, we only need two phases if the output current exceeds 20-30A (depending on Vin-max, Fsw, max ambient…
Hello,
I've numbered my answers to correspond with your questions:
1) That is OK for this device.
2) Webench models are based on simulation data correlated with bench measurements. Since there is real bench data included in the model, not all specific…
Part Number: LM5143DESIGN-CALC Other Parts Discussed in Thread: LM5143-Q1 Hi, Team,
Please let me confirm about "Effiency/Power Loss Analyzer shown in IM5143-Q1 Quickstart Design Tool. In the section of "Effiency/Power Loss Analyzer" in the file,…
Hi Abhishek,
I recommend using the LM25143 quickstart calculator: https://www.ti.com/tool/LM5143DESIGN-CALC
Set Vout = 20V first and derate the ceramic output capacitance accordingly. Then fix the compensation values and check the loop with Vout =…
Hi Andrew,
No, the slope comp is not applicable in that calculation. Take a look at the LM5143 quickstart calculator to assist with the design.

Hello Yx,
please use the design calculator and it will recommend the inductor value for you. Yes, when choosing an inductor for a buck, make sure ripple is 30-50% of IOUT.
